IMPROVEMENT IN MACHINES FOR PEGGING BOOTS OR SHOES.

Specification forming part of Letters Patent No. 34,370, dated February 11, 1862.

T0 all whom it may concern/.-

Be it known that I, MosEs MARSHALL, of Lowell, in the county of Middlesex and State of Massachusetts, have invented certain Improveinents in Machines for Pegging Shoes or Boots, of which the following is a full, clear, and exact description, reference being had to the accompanying drap/ings, making part of this specification, in which- Figure l is an elevation or side View of my machine, a portion of the case being broken away to show the parts within; Fig. 2, an underneath view of the same; Fig. 3, a perspective view of the peg-trough and feeding apparatus; Fig. 4, avertical section upon the line A A of Fig. 2; Fig. 5, a section through the peg-trough and feeding apparatus; Fig. 6, a view of the splitting-knife and the parts immediately connected therewith; Figs. 7, 8, and 9, details to be referred to hereinafter.

There are various difficulties in the way of applying an automatic feed of the peg-'wood to a hand-pegging machine,which it is the object of my present invention to overcome. Thus far it has not been found practical to apply such a feed Where the peg was cut off by a stationary knife on the descent of the pegdriver.

My present invention consists in feeding the peg-wood by an automatic intermittent feed on the descent of the plunger and splitting off the peg as the plunger rises; and my invention also consists is so forming and arranging the splitting-knife that it shall force the peg forward under the plunger as it is cut off, as will now be more fully described.

The operating parts are contained within a body or case B, to which the peg-trough C is screwed. The awl D, Fig. 4, is carried by a plunger E and is forced into the leather by the blow of a hammer upon the top of the plunger, and withdrawn therefrom by an india-rubber spring F, which strikes upon the cap-plate of the machine as the plunger descends. The plunger is raised in the usual manner by a spiral spring W, which encircles it. The peg-driver g is also carried by the plunger and descends to drive the peg when the awl enters the leather.

The strip of peg-Wood is entered at the open end a of the' peg-trough, and is fed intermittently to the knife o, as follows: The feeding-pawls b are pivoted to a sliding bar CZ, which is forced in the direction of its arrow to eect the feed by a spiral spring e and in the opposite direct-ion when the piston descends by the inclined block f, attached to the knife, Figs. 2, 3, 5, and 6. The bar G, to which the knife and feeding-block fare attached, is operated by a pin H, projecting from the plunger and entering a slot 't' in the bar. Immediately beneath the pin H is a short bar or pin Z. This pin is surrounded by a spiral spring n, which yields as the hammer strikes the plunger, and relieves the concussion which would otherwise take place upon the bottom of the slot. The spring n also prevents any rebound of the knife, which might otherwise interfere with the proper feeding of the peg-strip. The raising of the knife to drive back the bar d and cut off the peg is effected by the last upward mot-ion of the plunger E, the pin H striking against the bar G at the top of the slot t'.

Vhen the bar CZ is driven back by the rise of the plunger, as above stated, the pawls are carried back to take a new hold upon the pegwood m, Fig. 5. These pawls pass through inclined holes in a sliding plate q, which is held in place by a spring r. As the pawls are carried forward by their spring e at the last moment of the descent of the plunger, they are forced in by the inclined edges of the holes in the plate, and are thus caused to press upon the peg-wood and effect the feed. The bar q also serves to keep the pawls constantly in contact with the wood and in readiness for action. The peg-wood is fed up in contact with the peg-driver which supports the advance end of the wood until the knife comes in contact with its lower edge to cut it off. The knife is of such a thickness that it shall just occupy the space from which a peg is split, and thus as the knife splits off a peg it forces it in under the peg-driver, Fig. 4, ready to be driven on the next descent of the plunger, and as the space between the knife and the plate s is wider than the peg the latter drops so soon as it is cut into the tube t, from which it is driven at the next descent of the plunger.

The feeding of the machine over the shoe is' accomplished in a manner similar to that which was adopted in the machine for which Letterslatent were granted to me on the 5th day of November, 186i.

To the interior of one side of the body or case B is pivoted at cl2 a lever J, having on its upper end an irregular slot e2, cut through it, of the form seen in the drawings. In this slot works a pin E2, projecting from the plunger E, so as to vibrate the lever J back and forth as the plunger rises and descends. The pin E2 also passes through a straight slot m2 in the division-plate h2, and thus the plunger' is prevented from turning. To the bottom of the lever J is pivoted the feeding-point f2, which is attached to one end of the swivelpin a2, and is so actuated that on the rising of the plunger it shall first be thrust into the hole last made by the awl and then by the continued upward motion of the plunger be fed along so as to bring the peg and peg driver directly over the hole. On the descent of the plunger the feeding-point is first withdrawn from the hole, leaving it ready to be occupied by the peg, and is then carried back out of the way of the awl, whichv now descends to make a new hole, and on the plunger again rising the feeding-point enters this new hole and feeds the machine along. This is eifected in the following manner: The feeding-point, as before stated, is secured to the swivel-pin a2, and to the other end of this pin, and outside of the lever J is secured a tooth Y g2, which engages with a notch in a lever L2,

pivoted to the lever J. jz is a stationary stop secured to the body of the machine, and t2 is a movable stop, which is forced down by a spring c2, the office of the stops 3'2 2 being to hold the lever L2 in position at certain times, while at others it is allowed to escape from their control. The operation of this part of the mechanism is as follows: Vhen the plunger is up, Figs. 1 and 4, t-he end of the lever L2 has forced up the spring-stop 712 andis held stationary by the stops jz and t2, the point f2 remaining in the hole in the sole immediately beneath the peg-driver and peg. As the plunger commences to descend, Fig. '7, the motion of the pin E2 in the inclined portion of the slot e2 vibrates the leverJ to one side. While this is taking place, the upper end of the lever L2 being held stationary by the stops i2 and y2, this lever is vibrated and also the pin a2; but as the tooth g2 is held by the notch in the lever L2 and is moved with it t-he pin d2 is caused to turn, and the feeding-point f2 is withdrawn from the hole in the sole, as seen in Fig. 7. So soon as this has taken place the lever L2 strikes against a pin 2 on the lever J, by which the motion of the lever L2 upon its pivot is arrested, and its upper end slips past the spring-catch 2, when by the continued motion of the lever J the feedingpoint is carried back, Fig. 8, out of the way of the peg-driver and awl, which are now,while the pin E2 is descending through the vertical portion of4 its slot e2, left free to descend for the purpose of making anew hole and of driving a peg into the one previously made. As the plunger again descends, it is necessary that the feeding-point go through a different set of motions, which are produced as follows: While the pin E2 is ascending through the vertical portion of the slot c2 the feedingpoint remains stationary, and during this 1nterval the awl has risen clear of the path of this point. The pin E2 now enters the inclined port-ion of the slot e2 andthe feedingpoint begins to travel back, being still raised above and clear of the surface of the leather. On the feeding-point arriving opposite to the hole last made by the awl the upper end of the lever L2 strikes against the spring-stop z2, Fig. 9, by which the point f2 is forced down into the hole, and at this juncture the lever L2 strikes against a pin 3 upon its opposite side, by which its motion on its pivot is arrested and the parts are caused to travel with the lever J, the feeding-point causing the machine to move over the surface of the leather, while the upper end of the lever L2 pushes back the spring-stop t2, and the parts are again left in the position seen in Fig. l. The stop X, which rests against the edge of the sole as the pegging proceeds, is made adn justable in position by means of a screw s2 for the purpose of regulating the distance to which the pegs are to be put from the edge of the sole. A lever Y, pivoted to the pegtrough, Fig. 3, bears at its lower end upon a pin 5 on the bar d, and when this lever is pressed toward the body of the machine the feeding of the peg-strip is interrupted.

Operation: The stop X being adjusted by means of its screw s2, so as to brin'g the awl at the proper distance from the edge of the sole, and the trough C being replenished with peg-wood, (a strip of which is seen in Fig. 10,) the machine is ready for its work. The operator now grasps it in his left hand, at the same time pressing upon the lever Y t0 prevent the feeding of a peg while he strikes a blow upon the plunger and discharges the peg already in the machine. The machine is now applied to the sole, the lever Y is released, and a blow is struck upon the plunger with a mallet or hammer, by which the awl is forced into the sole and the first hole is made at the same time that the peg-wood is fed forward. As the plunger rises the awl is withdrawn from the sole, the knife is raised, and a peg is split off and forced in under the peg-driver. The feeding-point enters the hole just made by the awl and feeds the machine over the sole a distance equal to that between two adjacent pegs. On the next descent of the plunger the peg-wood is again fed forward, and the operation continues, each blow of the hammer upon the plunger driving a peg and making a new hole.

WVhen it is required simply to make the holes in the sole for the insertion of metallic nails, the feed of the peg-wood is interrupted by means of the lever Y, as above described.

Wha-t I claim as my invention, and desire ranged as to split 0E the peg and force it unto secure by Letters Patent, isder the peg-driver While the latter is up.
